Mostly a lot of small fixes since 2.6.10-rc3, with the biggest thing being
probably the CIFS update and the switch-over to the new DVB frontend
driver world order. Some MMC and USB work too, and ARM updates as usual.
Shortlog from 2.6.10-rc3 appended, with the full log from 2.6.9 on the
normal distribution sites.

reported from the server (rather than generated by the client).
Some apps require inode numbers to persist or inode numbers of
hardlinked files to match and this requires trusting the servers
inode number.

o [CIFS] cifs readdir rewrite fix resume key handling
o [CIFS] CIFS buffer management improvements part 1
o [CIFS] minor cleanup to cifs buffer allocation code
o [CIFS] fix size of cifs small buffers to just barely fit within
slab limit (which appears to be 116 bytes), otherwise they take 1
page each.
o [CIFS] Set inode number properly on new cifs_readdir code to
Windows servers
o [CIFS] fix error mapping on getfacl to windows and old samba
servers to map to EOPNOTSUPP so the kernel's fall back mechanism
works
o [CIFS] Update Kconfig to make CIFS POSIX ACLs dependent on xattrs
and fix related ifdef in fs/cifs/xattr.c
o [CIFS] Add missing quote to cifs kconfig item
o [CIFS] Make new cifs readdir code the default and rename the proc
entry to /proc/fs/cifs/ReenableOldCifsReaddirCode (which is off by
default, causing the new cifs_readdir2 code to be executed by
default)
o [CIFS] Fix endianness bug in new cifs_readdir2 in calculating dir
entry name length. Fix "badness in" message on rmmod cifs caused by
rename of /proc/fs/cifs/NewReaddirEnabled config switch (pointed
out by Shaggy).
o add direct mount options to optionally bypass the page cache on
reads and writes
o [CIFS] zero more of SMB param area on SMB allocation
o [CIFS] fix spelling of CONFIG_CIFS_EXPERIMENTAL ifdef in direct i/o
write
o [CIFS] cleanup various warning/debug messages
o [CIFS] add debug message for trusted and security xattrs
o [CIFS] Increase size of small SMB pool (and decrease number) and do
not zero the beginning of the header twice.
o [CIFS] parse ipv6 addresses on mount (ipv6 support for cifs part 2)
o [CIFS] Check right mid state on hung network responses. Fix remote
dnotify to be disabled by default. Fix dnotify endianness.
o [CIFS] Do not block on FindNotify response
o [CIFS] Allow peek to return less than smb header so we do not
prematurely kill session to server when socket stack is busy.
o Add support for module init parms for number of small and large
cifs network buffers and for maximum number of simultaneous
requests. Fix directio of userbuffers to use copy_to_user.
o [CIFS] remove sparse warning
o [CIFS] Remove sparse warning in use of cifs_write function
o [CIFS] Fix CIFS_MAX_MSGSIZE so it can be configured at
module_install time, allowing buffer size to be changed
o return the right return code on failed ExtendedSecurity mount to
SPNEGO enabled servers to avoid mount oops. Fix case in which tcp
stack only returns 3 bytes
o [CIFS] Fix path based calls to consistently allow up to PATH_MAX
(some were incorrectly limited to just over 512)
o Error mapping workaround for NT4 bug of reporting oldstyle DOS
error for ERR invalid level (shows up on attempts to do SetPathInfo
to NT4)

Merry Christmas!
Merry Yule to you too.
Not wishing to be too ungrateful to Santa but
- The broken AX.25 patches are not reverted so that doesn't work on some
networks
- It seems the security hole inducing exec_id change was not reverted
and I've not yet found any other changes that fix the same problem
(setuid_app >/proc/self/mem) in 2.6.10. It was actually quite nasty as a
hole because you can seek the fd to the right target address before
execing. With the other /proc changes did I miss something on this one
I'll check it all over in more detail when I generate 2.6.10-ac
(probably tomorrow), which will be nice as the patch will be a _lot_
shorter and USB storage a lot happier than 2.6.9 based systems.

Alas, It sort-of boots but is terminally slow. I see the log with
endless repetitions of "irq 18 nobody cared" and some trace, then
"disabling irq 18." Unfortunately it lies, after about 20MB of this I
decided it had no real intention of disabling irq 18 and tried to stop
it. After ten minutes I had to pull the plug and it's still cleaning
filesystems.
I will dig through the log after it gets back up, but there is clearly a
problem in the logic to ignore garbage irq's, or at least stop whining.
If there is any similarity between the traces I'll post, but I suspect
that it was one of those edge vs. level things by the behaviour.
Just a warning in case others are seeing a failure of irq disable to
actually work.

Can you send a (normal) dmesg output for this machine, and describe what
is normally on irq18?
It _sounds_ like it's a confusion between level and edge, with the usual
suspects. Does it go away if you disable acpi?

Here it boots and works, but I can't say that I have done any serious
testing. The following message appears in the kernel log:
Dec 25 11:38:09 lfs parport_pc: Ignoring new-style parameters in presence of
obsolete ones
Dec 25 11:38:09 lfs parport_pc: VIA 686A/8231 detected

[PCSPP,TRISTATE,COMPAT,ECP]
Dec 25 11:38:09 lfs parport_pc: VIA parallel port: io=0x378, irq=7
I don't understand the first line, and it wasn't there in 2.6.9. Could you
please explain what it means? I don't pass any parameters to the module. I
use module-init-tools version 3.0 although I know it is not the latest.

Somehow parport_pc.c ended up with mixed old-style and
new-style module parameters, but mixing them is not
allowed.
Use module_param() instead of MODULE_PARM() -- cannot be mixed.

That sounds like a configuration error, or not running depmod/modprobe
properly. svc_wake_up() &co are exported by the sunrpc module, and you've
apparently not loaded it..
As to what the "DV failed", it's apparently normal if DV is disabled,
whatever the hell that is. James will know whether it's something to
worry about..

DV is Domain Validation. It's a way of probing the SCSI bus to see what
type of transfer speeds and widths it can support. DV is part of the
mid-layer SPI transport class, which is where most drivers get it from.
However, this message is from the aic7xxx which does its own DV
separately from the mid-layer. As far as I can tell from the aic7xxx
code, it has a state machine model of DV and it prints this message if
it goes through an unexpected transition of that state machine, but I've
no idea from the message what actually happened. Everything seems to
proceed normally, since the device that caused the problems is later
configured at 160MB/s (the maximum the aic7xxx can do).

Thankfully I missed something as the test app shows
static char foo[5]="GOOD";
int main(int argc, char *argv[])
{
lseek(1, (unsigned long) foo, 0);
if(write(1, "BAD!", 4) != 4)
perror("write");
write(2, foo, 4);
}
Running ./a.out >/proc/self/mem produces the desired write error still
in 2.6.10

Hmm, this is probably "big order" allocation failing during
resume. hugang's patch could help here...

Can you try this one? It would be nice to have reproducible way to
trigger this before trying to fix it, through.
[Patch is for 2.6.9something+my bigdiff, may need small tweaks]

It's for i386, isn't it? Will it work as expected on AMD64?
RJW
My ps/2 keyboard (an relatively uninteresting Labtec 104-key model)
doesn't work with 2.6.10, although 2.6.9 and the BIOS seem to have no
issues with it. I've gone through the changelog and double-checked my
.config (attached), and don't see any obvious problems... any thoughts?

Ouch, no, it probably will not work on amd64. Some assembly tweaks
would be needed.
Anyway here's that patch ported to 2.6.10+my_bigdiff (just in case
anyone has the same problem on i386).
hugang, I noticed you changed collision code to use a bitmap. This
should reduce complexity from O(n^2) to O(n) [good!], but I'm
concerned about bitmap size you need -- it seems to be big order
allocation. Perhaps you could reuse PageNosaveFree or something like
that?
Also that code should be pretty much separate from "convert pagedir to
linklist", right? Could you separate them?

I've seen no errors, it just doesn't work any more. (It definitely
worked with 2.6.9.)
Unloading/reloading the module doesn't appear to help either.
(This is experienced on an IBM Thinkpad X31.)

OK, I figured it out (I think). I normally go through a Avocent KVM
switch (USB), to share the keyboard and mouse between multiple systems.
Unfortunately the keyboard died a week or so ago, so I plugged a ps/2
model directly into the main box as a temporary measure... but didn't
think to disconnect the KVM. After doing so, 2.6.10 correctly detects
the keyboard on bootup and everything seems to be working correctly.
I haven't pursued it any farther, although I'd be happy to do so if
anyone thinks it would be beneficial. My guess is that only a single
keyboard is allowed, and 2.6.10 simply saw the USB one first. Not sure
if that was caused by an explicit change in the code, or merely due to
the order in which the drivers were linked in. Either way, I'm up and
running. ;-)
Thanx for your assistance!
Priorities this week...
Having at least a -rc or maintaining a 2.6.XY.Z branch would avoid
these problems in my very humble opinion.

It looks like growing the inode and/or dentry cache before suspend does the
trick. It seems that updatedb (again) is quite good for this purpose but
it's not 100% "effective".

I've just had one of those on 2.6.10-mm3:
Has this patch been ported to x86_64? Or is there a newer version of it anywhere,
or an alternative?

Was that hugang's patch we were talking about?
Anyway ugly workaround for this is to just try harder to free memory during
suspend... Just do free_some_memory five times with msleep(200) in between.
